Taking to Instagram on Sunday morning, this time intentionally, Harris said she had woken to several messages trying to alert her to what was happening in her bedroom.

"Er, this is a bit awkward," she wrote.

"Not sure how I managed to turn on Instagram Live in my sleep (I probably knocked it on accidentally while blindly fumbling for water on my bedside table because pregnancy makes me SO DAMN THIRSTY) but I hope it was entertaining.

"Anywhooo, my Saturday nights are clear lit. Yours must be too IF YOU'RE WATCHING A LIVE STREAM OF A SLEEPING PREGNANT LADY SNORING YA BLOODY WEIRDOS!!!"

The popular host took it all in good humour, replying to comments on the post, including one that noted the hilarious mistake was "peak Harris".
